## Properties

### Flat

> Source set: Common

```kotlin
public val Flat: FoldState = FoldState(0)
```

Represents a flat fold state, where the window's display area on a foldable device is
flat (either fully open or closed). It's the default state for non-foldable devices,
or when the window does not span across a hinge or fold (such as in split-screen mode
on a single panel).

### HalfOpened

> Source set: Common

```kotlin
public val HalfOpened: FoldState = FoldState(1)
```

Represents a device in a semi-open state. The window spans across a hinge or fold,
splitting the display area into two logical parts.
